To be honest out all of those are excellent psu's and there's no wrong choice here. One thing I would recommend though, is looking into something modular. I have a TX750 and the only qualm with it is that I have nowhere to put the extra cables

It can be tough to pick and choose within a group of quality PSU's like that (within the same price range too).

You really can't go wrong with any of them.

To nitpick more make sure that your choice (compared to the rest);

1. Has the highest efficiency at your estimated load (gaming) usage, and at idle (if possible).
2. Has the maximum number of included cables for your needs (multi-GPU, hdds, optical, etc...).
3. Has cable lengths that are sufficient for extended routing to your motherboard.
4. Has the lowest operating temperatures and fan noise (if these two things concern you).

You might get all of these things in your choice, or only a few. Comparing the above things can easily help narrow down your choice. Good luck.
